Here's what I get
Explanation:
Both diamond and SiO₂ are network solids. Their atoms are all joined together so a crystal of either diamond or SO₂is one giant molecule.
Structure
In diamond, each C atom is covalently attached to four other C atoms.
The structure of SiO₂ is like that of diamond. The difference is that there is an O atom between each atom of Si.
Properties
Both substances are
- High-melting
- Hard
- Insoluble in both polar and nonpolar solvents
- Poor conductors of electricity
A. The molecules of solids are close together and compact, liquids are spread out but not too far apart, and gas molecules are really far apart.
B. Increase in temperature causes pressure to go up. Decrease in temperature cause pressure to go down
Sodium is a metal that belongs to group 1 of the periodic table.
<h3>What is my favorite element?</h3>
My favorite element is sodium. Sodium is found in group one of the periodic table. The element is univalent and also forms univalent positive ions. Like every other metal, sodium is able to react with dilute acids to liberate hydrogen gas.
Sodium is a light metal and is known to react with mercury to form the sodium mercury amalgam which is obtained during the electrolysis of sodium chloride. All of the compounds that are formed by sodium are ionic in nature. However the hydrides of sodium are unstable.
Sodium is highly reactive thus it must not be exposed to air since it could ignite spontaneously in air. As such, sodium must be stored under paraffin oil. All the compounds of sodium are ionic in nature.
